The Norwegian Sea (Norwegian: Norwegian) is a continental sea in the North Atlantic Ocean (because the north is located in the Arctic Circle, it is often classified as the boundary sea of the Arctic Ocean), which is located in the northwest of Norway, between the North Sea and the Greenland Sea.

The Norwegian Sea is connected with the Icelandic Sea in the west and the Barents Sea in the northeast. In the southwest, the submarine ridge between Iceland and Faroe Islands separates the Atlantic Ocean from the Norwegian Sea. As for the north, the Jan Mayan submarine ridge is the dividing line between the Norwegian Sea and the Arctic Ocean. To the east is Norway, and there is a fjord eroded by glaciers on the coastline.

Located between Svalbard, Iceland and Scandinavia. Area 1.383 million square kilometers, average water depth 1.742 meters, and maximum water depth of 4487 meters. The sea area is bordered by the Arctic Ocean in the north, the North Sea in the south and the Atlantic Ocean in the west, and its geographical position is very important. It is a maritime transport corridor in northwest Europe. There is an east-west Jan Mayen fault zone in the middle of the Norwegian Sea, which divides the ocean into two parts, the Lofton Basin in the north and the Norwegian Basin in the south. The eastern part of the sea area was eroded and accumulated by Nordic land glaciers, forming a fjord-style coast and underwater hills and shoals outside the fjord. The seawater near fjords and underwater shoals is rich in nutrients, and it has become an important fishing ground in this area, rich in cod, herring and whitefish. Most of the Norwegian Sea is located in the Arctic Circle, with high latitude and low temperature, but the sea water will not freeze in cold winter, which is mainly regulated by the powerful North Atlantic warm current. The surface water temperature in this sea area is 10℃ higher than that in Greenland Sea and Baffin Bay at the same latitude. The main coastal ports are Trondheim and Narvik in Norway. The Norwegian Sea is rich in natural resources. Since 1993, a large number of crude oil and natural gas have been produced. In addition, it has been suggested that the Norwegian Sea can be used as a storage place for carbon dioxide to reduce the greenhouse effect. Ocean currents are in the Norwegian Sea and the Greenland Sea, and the surface seawater sinks to the bottom of the sea for 2-3 kilometers, so the water on the bottom of the sea is very cold and has high oxygen content. Therefore, there is a warm sea surface current and a cold submarine current on the west coast of Norway. The East Icelandic Current in the Norwegian Sea brings cold water to Iceland in the south, and then turns eastward along the Arctic Circle. The Norwegian current is a branch of the Gulf Stream, which brings warm water masses to the north and keeps Norway's climate mild and humid. In addition, the Norwegian Sea is also the source of deep water in the North Atlantic. The Norwegian Sea won't freeze because the warm and salty Atlantic Ocean current passes through it. This sea area is rich in fish, including cod, herring, sardines and anchovies. Scientists believe that the fluctuation of ocean currents is an indicator of climate change, so the ocean currents flowing through the Norwegian Sea are closely monitored. Seafood Norway is one of the three largest seafood exporters in the world. Norwegian seafood includes wild fish and shellfish caught in the Norwegian Sea and Barents Sea, as well as farmed fish from hundreds of marine farms in Norwegian coastal waters. Norwegian products are cherished for their delicious and nutritional value, and their fresh, frozen and processed products have been exported to more than 50 countries. The waters of the Norwegian Sea are one of the best fishing grounds in the world, and it is the habitat of more than 200 kinds of fish and shellfish. Today, the most famous aquatic product in Norway is cod eggs, whose Norwegian name is "skrei". This kind of cod caught in the cold sea water on the northern coast of Norway is favored by cooking experts all over the world. Other popular fish and shellfish species include herring, mackerel, various white salmon, prawns and crabs. A highly modern fishing fleet and strict management regulations help to ensure the sustainable development of Norwegian fisheries. Norway Sea Norway is a pioneer in developing modern mariculture. Marine farms are all over the Norwegian Sea, and marine farming has become one of Norway's major industries. Aquaculture produces a little over 40% of the seafood exported by Norway. Norwegian salmon is the largest exported farmed fish, which is highly valued for its attractive color, good taste and production environment. Other cultured species include salmon and trout and various shellfish. In addition, Norway is making efforts to increase the variety of commercially farmed seafood, such as flounder and cod. Seafood is a good source of digestible protein, vitamins, minerals and main fatty acids. Norway can provide all kinds of seafood, including fresh-keeping, freezing, smoking, air-drying, salting, fish chops and other processed products, such as breaded, canned and salted seafood. Norwegian salmon is also very popular in the quality-oriented Japanese sushi market. The biological Norwegian crayfish (scientific name: norvegicus) is a species and genus of Carnivora. Slender, with slender claws, orange or pink, about 24 cm long. They are mainly distributed in the East Atlantic Ocean, the Norwegian Sea between Norway and Iceland in the north and the waters near Portugal in the south. In the Mediterranean region, crayfish in the Norwegian sea are not common; Only in the northern Adriatic Sea is the active area of crayfish in the Norwegian Sea. Their tails have strong muscle energy and rich meat, so they have become popular seafood dishes. Because the price of Norwegian crayfish is cheaper than that of ordinary European crayfish, Norwegian crayfish is cooked every major festival or celebration in Spain and Portugal. The port of Trondheim was originally named Trondheim. The central port city on the west coast of Norway is the third largest city in Norway. It is adjacent to the Norwegian Sea, located in the southeast of Trondheim Fjord and at the mouth of Ned River. Population 1.54 million, which was once the capital of Norway in the Middle Ages. Trondheim is one of the oldest cities in Scandinavia, with a history and tradition of over 1000 years. In 997 BC, the Viking king revived the whole city and officially named it Nedros. Trondheim is a shipping hub and a famous university town, with the largest research center in Europe and the world-famous Norwegian University of Science and Technology. Trondheim is located in the center of Norway, 500 kilometers away from Oslo, and you can travel all over the city in one day. In 997, King Olaf I of Norway (reigned from about 995 to about 1000) established the city. In the14th century, it was the capital of Norway. Industrial center, with shipbuilding, canned fish, wood, paper, metallurgy and textile industries. It has railway connections with ports and cities in Norway and Sweden. Maritime transportation is developed. There are modern oil ports and commercial ports here. Foreign trade is booming. There is the most magnificent church in Scandinavia. If Trondheim is not the "most perfect city in the world" as stated in the official advertisement, it can at least be said that its geographical location makes people feel very comfortable and the urban layout makes people feel very reasonable: commercial institutions and historical and cultural buildings form a prosperous and beautiful urban landscape in harmony, while those local industrial departments are dotted with green suburbs. The city used to be a residential area of the rich Earl Ladd family. Haakon Sigosen, Earl of Rade, ruled Norway in this fertile land until he was killed by Olaf Trieger Watson in 995 and died. The latter (Olaf I) established the "Trondheim County Trade City" here two years later, and later renamed it "Nedros" (named after the "Ned River"). The cathedral in the city still uses this name, but most local residents still habitually call the city Trondheim. Trondheim's fame and prosperity were first attributed to Norwegian Olaf II of Norway. The later Norwegian patron died heroically in the Battle of Starr, Stickler, and his body was buried in St. Clemens Church built in 10 16. 103 1 year, when his body was excavated again, people were surprised to find that it was still fresh and undamaged (spring water soon appeared in this place). Therefore, Olaf II of Norway in Norway was honored as a "saint", and Nedro soon became a pilgrimage site in medieval Norway. Pilgrims who come to worship are most concentrated around the "St. Olaf's Day" on July 29. 1897, on the occasion of the 900th birthday of Norwegian Olaf II of Norway, Trondheim resumed the "St. Olaf's Day", and now people have ten days off every year to celebrate this festival. During World War II, Trondheim was the center of resistance movement in the occupied areas of Norway. Today, Trondheim is not only a railway and highway transportation hub leading to Oslo, but also an important commercial port and fishing port. Narvik's old name was "Victoria Haven". A city in northern Norway. On the peninsula at the eastern end of Offord Fjord. The population is 65438+900,000 (65438+980). It is an ice-free port because there is a warm current from the North Atlantic. The terminal of the electrified railway between northern Sweden and Stockholm. Since 1883, it has been the main export port of Swedish iron ore. Fishery is developed. 1940, the British and German navies fought fiercely here. 1 in April, 939, Hitler had issued a battle plan to wipe out Poland forever, and made a surprise attack on Poland in September,1. Due to the pressure at home and abroad, Poland's allies Britain and France were forced to declare war on Germany on September 3, but they did not send troops to try to encourage Germany to attack the Soviet Union. At that time, there were only 23 divisions in Germany's western front, while the British and French allied forces had a huge force of 1 10 divisions. The "sit-in war" made them lose their fighters and the Germans began to move westward. 1940 On the morning of April 9, the Germans raided Denmark and Norway, occupied Denmark for 4 hours, and occupied Oslo, the capital of Norway, in the evening. Norwegian troops retreated to the mainland to continue fighting. British and French troops landed in the Norwegian coastal city of Narvik, but they were bombed by German artillery. Although they fought fiercely, they finally had to retreat because of serious casualties. On June 10, the Germans occupied the whole of Norway. The battle of Narvik was an episode in the European battlefield of World War II, but it was a moment of national mourning in Norway. France built a monument to martyrs to commemorate the martyrs who died in the battle of Narvik. This is the second anniversary stamp of the Battle of Narvik 1952 issued by France. Narvik is the northernmost ice-free port in the world, which is connected with Kiruna by railway. Narvik is the mouth of Kiruna ore, and the town has developed because of ore transportation. Pollution In June 5438+1October 65438+March 2007, the wreckage of the Greek cargo ship was towed to the shore of the sea near Bergen, a city on the west coast of Norway. According to the report of Norwegian News Agency on the same day, this large cargo ship 12 ran aground when passing through the sea near Bergen that night, and the hull of 180 meters long was hit by huge waves and broke into two parts. It is estimated that about 270 tons of fuel loaded on this cargo ship has leaked out, causing serious pollution to Norwegian waters. At the time of the accident, the 20,000-ton "aircraft carrier" was preparing to sail to Murmansk, Russia to load. After receiving the alarm, the Norwegian authorities immediately dispatched coastal rescue teams and helicopters for rescue. By the early morning of 13, all 25 crew members on board were rescued. The cargo ship "aircraft carrier" has no cargo, but there are about 600 tons of fuel on board. As of noon on 13, fuel was still seeping into the sea. The strong winds and huge waves of 65,438+07 meters per second make the rescue work very difficult. The oil pollution on the nearby coast spreads rapidly, and the beautiful beaches and the habitats of local birds are seriously polluted. According to the Norwegian authorities, this fuel leak is one of the most serious accidents in Norwegian history. It may take at least half a year to completely clean up the leaked fuel, which will have a very serious impact on the nearby natural environment. The Greek cargo ship "aircraft carrier" broke in two in the waters near Bergen, a city on the west coast of Norway.
